Fig.5.2 The input macros implemented with Petri nets
(Page 2/2)

On this page, there is the list of problems, as visible on page 130 of copycat82 which contains two of the input macros:

• macro-gate input-"priority-++"
• macro-gate input-"exclusive-or"

The other three input macros are on the page 129, and the output macros are on the page 132. The page copycat82 Gate Problems is about the consequences.
